FIELD: physics.
SUBSTANCE: vacuum insulation body comprises at least one vacuum-tight shell and at least one vacuum region that is surrounded by a shell. Casing is provided with at least one opening, in particular at least one vacuum opening for evacuating the vacuum region, and at least one adsorbent material is contained in the vacuum insulation body, which is partially or completely disposed in the region of said opening. At least one plate is located around the opening and inside the vacuum region, which forms the wall of the space in which the absorbent material is located. Between the absorbent material and the opening, at least one shaped piece is provided which has one or more holes of the shaped part, the cross section of the flow of which is greater than the cross section of the opening of the shell opening.
EFFECT: use of inventions makes it possible to create vacuum in vacuum isolation in a reliable and economical way.
